When Li Yuanhong heard something moving on his head, he looked up and saw that the ceiling in the middle of his head slowly cracked into a huge square, and then the huge ceiling slowly fell down. When the whole ceiling came down, Li Yuanhong realized that it was an elevator. Tens of thousands of years ago, human beings knew how to make elevators.

Li Yuanhong stepped up and down the stairs, but he didn't do much. Soon the elevator went up slowly, and soon the whole ceiling was in perfect harmony. If you don't know that the passage is on the ceiling, you won't find it in your lifetime.

The elevator slowly ascended and soon took Li Yuanhong to the next floor.

As soon as you enter this floor, the whole space lights up immediately. I don't know how prehistoric civilization did it. The whole room is illuminated brightly, but you can't see any light bulbs and tubes. Those soft lights come out from the wall, and the murals around are clearly visible.

There are many monstrous monsters on the mural. They step into the earth through a huge portal. Facing these monsters, a group of panic stricken human beings are facing them. In fact, if you look carefully, there are still differences between those human beings and modern people, not only in clothing, but also in facial features.

Li Yuanhong didn't pay attention to these details. Instead, he went on to look at all kinds of battles. There were victories and defeats in the battle between human like civilization and giant beasts, but on the whole, they were still losing. In the last picture, the prehistoric civilization established a huge magic circle and sealed the transmission array. However, due to the huge cost of this prehistoric civilization, civilization also gradually declined. In particular, the giant beast caused great damage to the environment of the earth at that time, and most of the earth's creatures were extinct, which forced the prehistoric civilization to migrate.

When Li Yuanhong saw the spaceships used by the alien migration, he was a little lost in his mind. How could those spaceships look like flying saucers in legend?

After reading the murals, Li Yuanhong roughly understood that the alien giant had not invaded the earth more than once. The Naga clan was definitely not the first race to be harmed by the giant beast.

After seeing the murals, Li Yuanhong moved his eyes to the center of the stone chamber, where there was a magic circle. In the middle of the magic array was the magic portal he had seen many times.

Of course, Li Yuanhong recognized that this was the transmission array he was looking for at a glance, so he planned to go to the transmission array. However, Li Yuanhong suddenly stopped, his feet hanging in the air, almost trampled on the magic array outside the transmission array.

in fact, there will be corresponding magic array outside the transmission gate, which is why Li Yuanhong did not pay too much attention to this magic However, when his feet were about to step on the magic array, he felt a very uncomfortable electric shock from the tip of his hair along the heel path. Li Yuanhong had several times before, without exception, warning of danger.

So Li Yuanhong quickly drew back the steps he was about to take, and then he looked at the magic array carefully.

after a close look, Li Yuanhong found that the magic array was bigger than the magic array seen before. In fact, it was not big, but a magic array was added outside the original magic array, and the extra magic array was an attack magic It is also a high-level attack array. As long as Li Yuanhong steps into it, I'm afraid it will be blasted to pieces by this array.

"Damn it, who is so immoral and wants to kill me by making such a thing outside the transmission array?" Li Yuanhong scolded secretly, so he began to look for the mechanism to shut down the array outside.

In fact, this mechanism is very easy to find. It's in the corner of the stone house. It's very abrupt. You can find it if you are a little more careful.

In fact, it's not surprising that the mechanism is abrupt. It's just that the magic array was added later. Judging from the traces of the magic drawing, it should not take long. It seems that the demons added it temporarily. It's estimated that the demons were afraid that someone would damage the portal, so they set up such a defense magic array. However, their craftsmanship is so poor that the magic array can't be switched on and off with the original To the stone chamber together, it seems so abrupt.

Li Yuanhong carefully closed the magic array, and then walked to the edge of the magic array. Then he took out a metal rod from the space and threw it into the magic array. Seeing that the magic array did not respond to anything, he walked in with confidence.

Li Yuanhong walked safely to the center of the magic circle. He took out the crystal from the space and put it into the portal. As long as the portal was opened again, the whole portal would explode. At that time, the demons who entered the portal would disappear in the black hole space forever.

Of course, the creatures standing in this room will not feel very good at that time. Li Yuanhong had seen the terrible situation of those cave people being bombed before, so Li Yuanhong could only express his sorrow to those demons, hoping that their skin would be thick enough to not be too ugly when they were killed.

After everything, Li Yuanhong has restored the magic circle in the outer circle. Li Yuanhong doesn't want those demons to notice anything, otherwise he will fall short.

However, there is another problem for Li Yuanhong, that is, how to get out. You should know that there is fog for cover when you come in, but there is no fog in the pyramid. If you do something in the pyramid, the hell dogs will find something wrong, so they can only find another way out.This suddenly reminds Li Yuanhong of the two copper doors. The copper door he came in was to the portal, and the copper door that demons were afraid of. Where did it go?

Li Yuanhong's heart moved for a moment, but he still denied the idea. Even the devil felt afraid, so he still didn't want to die.

When Li Yuanhong was in a state of unconsciousness, he inadvertently looked up at his head. At this time, Li Yuanhong found that the top of his head was somewhat different.

Before several stone rooms, the ceiling is flat, except for some murals, there is no decoration. But there is a concave place in the ceiling. If you don't look carefully, you can't see it. You know, this stone room is illuminated by light, and it's not as dark as other stone rooms. But look carefully, that concave place, just out of the dead corner of several lights, maybe this is the visual black under the lamp.

"Is there anything else on top of your head?" Li Yuanhong said in his heart.

Before the end of the world, Li Yuanhong saw many kinds of pagodas. During the maintenance, he found the treasures of the ancient pagoda hidden in the dark lattice on the top of the pagoda. They were all national treasures among the national treasures. There was even a pagoda. He even found the relic of Sakyamuni Buddha 2000 years ago.

As such news is too shocking, how could Li Yuanhong forget that this is a site of prehistoric civilization tens of thousands of years ago. I'm not sure that these prehistoric people would also hide some things.

So Li Yuanhong took out the tools to climb the wall from the space. These tools can make Li Yuanhong a spider man and walk on the ground on the steep mountain wall.

Li Yuanhong climbs up the roof carefully. The reason why Li Yuanhong is so careful is that the attack magic array below has started. If Li Yuanhong falls down carelessly, he will be attacked by the magic array. Therefore, Li Yuanhong is extremely careful.

Fortunately, Li Yuanhong's climbing equipment is good enough, and the suction is strong enough. Li Yuanhong climbs on the stone wall, just like sticking to it.

Li Yuanhong came to the center of the roof smoothly. At this time, Li Yuanhong saw that there was a small concave hole in the middle of the roof. There was a pull ring in it. Obviously, it was a mechanism to open the switch leading to the top.

Li Yuanhong pulled down the pull ring and listened to the "click" on his head. Then the ceiling slowly opened and a vertical ladder was lowered. Li Yuanhong climbs up the hidden space along the vertical ladder.

There was no light on the upper floor. It was pitch black. Li Yuanhong quickly turned on the headlamp on his head.

As soon as the headlights were on, Li Yuanhong immediately saw the facilities in the house. The whole room is not very big. It is only half the size of the room below. This is the room. It is surrounded by shelves made of stones, and many items are placed on it. However, due to the long history, most of the items have already become dust. Only a few of them can be seen as they are. However, it is difficult to say whether they can be restored.

However, in the middle of the stone house, there is also a stone table with a box on it. Due to too long time, the box is covered with dust. Now we can't see what material is made of and what is inside. Obviously, the box in the middle is the most valuable one in the whole room.

Li Yuanhong carefully explored the surrounding area with his real eyes. He did not find any mechanism traps or magic array. It's just slowly approaching the stone table in the middle.

When he was close to the stone table, Li Yuanhong carefully brushed the dust off the box, and then he saw that it was a crystal box. The box was not small. It could be regarded as a small treasure chest. Although there was no decorative pattern on the whole box, it looked simple, but it was a whole crystal, and the water was crystal clear. It was perfect without any impurities. If you didn't pay attention, he thought it was a glass box 。 Li Yuanhong's spirit was greatly affected by the cold and cool hands of the box. Obviously, this crystal is not an ordinary item.

There was no lock on the box, so Li Yuanhong didn't have to worry about unlocking it. So he gently opened the lid and found that there was a crystal skull inside.

Li Yuanhong was stunned. Li Yuanhong was very clear about the crystal skull. It was found in the relics of Mayan civilization. Until now, those scientists have not found out what to do with it. Why is there another one here?

Li Yuanhong is not the time to study carefully either, so he put all the crystal boxes into the space and have time to study in the future. Just as Li Yuanhong was about to leave the round table and look at the four sides of the shelf, suddenly the light swept over the round table. Li Yuanhong found that there were some scratches in the place where the crystal box was placed before the round table.

In fact, the whole table has been covered by dust. If Li Yuanhong had not taken away the crystal box, the lines on the table would not have been exposed.

Li Yuanhong quickly lowered his head and wiped off the thick dust on the table to reveal the true face of the table.

The whole tabletop is made of granite. Although it has been tens of thousands of years, the stone table still keeps its original appearance. However, Li Yuanhong did not pay attention to the material of the stone table. Now Li Yuanhong is concerned about the patterns of the paintings on the stone table.
